2. John Osborne : GS-SEM Civil Engineering 18 May 2009 Report on behalf of CLIC Civil Engineering and Services (CES) WG CTC 18 May 2010 CES studies for CDR : 1. Tunnel cross section 2. Injection Complex 3. BDS Layout 4.Experimental Area Layout 5.Summary

3. John Osborne : GS-SEM Civil Engineering 18 May 2009 1.Tunnel cross section

4. John Osborne : GS-SEM Civil Engineering 18 May 2009 4 4.5m tunnel for CDR as agreed in 2009

5. John Osborne : GS-SEM Civil Engineering 18 May 2009 5 Drawbacks with 4.5m tunnel identified in 2009 Positioning of electronic racks not ideal Solution : Re-position onto tunnel floor, but possibly means deleting safety barrier Difficult to access ‘tunnel wall’ side of modules Solution : remove entire module for access ? Access to Drive Beam dumps Solution : Local Tunnel enlargement to allow ‘ladder’ access (see next slides) Impact from vibration from floor embedded pipes Solution : Further studies in TD Phase Reduced space due to transversal ventilation and perhaps not sufficient cooling power Solution : Study longitudinal ventilation system during TD Phase No space for vehicle powering ‘monorail’ and integration conflict Inductive powering for vehicle ?

30. John Osborne : GS-SEM Civil Engineering 18 May 2009 Overall layout updated (full symmetry)

31. John Osborne : GS-SEM Civil Engineering 18 May 2009 5. Summary Will continue to try and ‘freeze’ CE layouts at monthly CES meeting. Next major issue is amount of space required for Power Converters. Martin Gastal is gathering input from other technical services for experimental hall (CV,EL etc) Costing for CDR required for all technical infrastructure by September with assistance from Amberg consultants (same CE consultants for ILC) Draft layout for CDR Chapter ‘Civil Engineering and Services’ has been submitted to Hermann Next CTC 22 June specifically about tunnel cross section (4.5m,5.2m or 5.6m)

32. John Osborne : GS-SEM Civil Engineering 18 May 2009 5.6m first DRAFT
